"To all 1071 cm it may, concern lie? it known that l, GEORGE W. KIRK-PATRILK, a citizen of the United States, and

sites, the object being a resident of Rochester, 'in the county of l/lonroe and State oi New York, have 111-:

Vented anew and improved Sprinkling ."Device for Fire Protection, ofwhich the ollowzng 1s a specification.

"'lt hisinvention relates to sprinkling deto provide a sprine lrlingdevice, preferably comprising a rotat lngrspr nkl inghead with mechanismfor con- F trolling 1 the. direction of the stream or astreamsofliquidissuing therefrom in'such a: way as to overcome the tendency to a defflection thereof by a current of air.

In carrying out my invention I may make use of a revolving sprinklerhead which is attached tea rotatable supply member, the

'p'arts bing so conformed that the main direction of the spray or streamfrom the revolving sprinklinghead is deflected from a,perpendicularwhile'the axis of the revolving sprinkling head is directedat any desired point of the compass. The supply member to whichtherevolving sprinkler head is attached is supported to rotate upon avertical axis and by means of mechanism permitting the free rotation ofthe parts on such vertical axis, while the stream issuing therefrom isdeflected from such vertical axis and is caused to impingengainst andcause the rotation of the revolving sprinkler head. To the supply memberI attach a wind vane adapted in its operation to direct the streamsissuing-from the sprinkler head against the wind or current of air.

In the accompanying drawings 1' have shown that embodiment of 'myinvention adapted to use in protecting the roof of a building againstfire without limiting myself, howevento such or any particular embodiment thereof.

Such drawings" are as follows,Figure 1 is a side elevation showing therotatable supply member and the u per and lower ends of the extension tot e supply pipe leading thereto shown partly in section.

Application filed August 12, l .911. Serial No. 643,714.

Similar-parts are designatedby similar reference characters throughoutthe several figures of the drawings.

Referring to the drawings,-H represents a part of thereof of protectedextending upwardly through which is seen the supply pipe P in vertical 1engagement central section making threaded at its upper end with a fixedextension memer D between the shoulderedlower end al of which andtheupper end of the pipe P the building to be there IS clamped theperforated metallic the-central orifice rotatably'reoeive the for-thepurpose to be washer member w, which 15 adapted to explained.

Upon the roof H there may preferably be member U extend secured atubular jacket ing upwardly within-a'hood member T-carriedby theenlarged lower end d ofthe (22- tension D to prevent'the water fromentering the building inside of the ember U, at the bottom of which isseen a flange u for securing the same to the roof.:

The rotating supply member E comprises a hollow its lower and larger enda perforated member 6 into, which there may be secured the upper end ofthe rodR freely rotatable as above mentioned in the member 10 andoperating to brace the parts against the action of the wind and thereaction of the issuing stream Onto the upper and smaller end of themember E there may be secured a sprinkler head, shown in this instanceat S, as of a well known construction, having the revolving vane sthereon operating in the usual way to divide the issuing stream into aspray and throwing the same in all directions outwardly and away fromthe'axis' of its rotation.

' The member E is provided on its convex side with a projecting-flange oto which issecured the wind vane by means of rivets or screws r. 6n thelower end of the member E there is threaded the collar C while castingand hasvext'ending across ion the lower end of the member E and the col-The operation of the device is as'follows;-The apparatus being installedin the manner indicated in the drawings and the pipe P being connected,through the medium of any suitable valve, with a suitable source ofsupply of Water under pressure, the water as it is forced through thepipe P and ex tension D enters the member E and passes I therethroughand outwardly therefrom at causing the same to rotate and is the openingindicated in dotted lines in the upper left hand end of this member inFig. land impinges against the rotating vane s also deflected therebyinto a fine spray While the .upon its vertical rotatably connected withsaid extension member, and having a passage therethrough terminating inan outlet adapted to discharge the liquid at an angle with the axis ofrotation of such element, a Wind vane on said element, a bracing rodextending longitudinally of and within said extension member, meanscarried 'by said rotatable element for securely holding one end of saidrod,

and a suitable bearing located in said pipe' extension Within which theother end I 0 said rod is freely rotatable, said rod adsi'iited to bracethe parts against the wind and the reaction of the issuing stream, andsaid vane adapted to control the direction of discharge of the issuingstream.

2. In a device for the a supply pipe connected with a suitable source ofliquid under pressure, a member forming an extension to said supplypipe, an element rotatably connected with said extension member andhaving a passage therethrough terminating in an outlet adaptpurposedescribed,

ed to discharge the liquid at an angle with the axis of rotation of suchelement, :1 revoluble sprinkler head, secured to the outer end of saidelement, ;a Wind vane on said element, a bracing rodextendinglongitudinally of and within said extension member, means carried bysaid rotatable element for securely holding one endof said rod, and asuitable bearing located in said pipe extension Within which the otherendof said rod is freely rotatable, s'aid rod adapted to brace the partsagainst the wind and the reaction of the issuing stream, and said vaneadapted to control the direction of, discharge of the issuing stream.
